The eggs of the Marsh-Titmouse and those of its allies, P. 

 dresseri and P. horealis, cannot be separated from each other by 

 any character. They are of a rather pointed oval form, and while 

 some have a slight gloss others are devoid of gloss. They are 

 -white, speckled and spotted -with two shades of chestnut. The 

 markings are everywhere sparse, except at the broad end, where 

 they are, in many specimens, dense, and form either an irregular 

 zone or an ill-defined cap. Many examples, however, are evenly 

 marked all over with very small specks. They measure from -59 to 

 •66 in length, and from -lo to -52 in breadth.
